Benefits of technology

This patent describes a system that produces a type of algae with less harmful substances. The system also results in wastewater with fewer contaminants. When the two are combined in a growth system, the algae are more likely to grow and last longer because they have fewer contaminants.

Problems solved by technology

The algae grown in this manner also has a longer shelf life due to the lack of contaminants within the harvested algae.

Embodiment Construction

[0034]In this continuation-in-part, a particular use of the algae harvesting methods and apparatuses described in U.S. patent application Ser. No. 13 / 865,087 (the “Parent Application”) is presented. In the Parent Application, an apparatus having a first stage flocculation tank and a second stage flotation tank is described. This description is reproduced below under the headings: “First Stage Flocculation Tank” and “Second Stage Flotation Tank.” This two-stage harvesting process produces an algae biomass having a reduced concentration of contaminants.

[0035]The Parent Application also describes that by using an electrode made of a titanium ruthenium alloy, wastewater can be treated using the two-stage process to remove ammonia and other contaminants from the wastewater. The use of an electrode made of a titanium ruthenium alloy within the two-stage apparatus is described below under the heading: “Additional Features Or Variations.”

[0036]It has been found that the algae biomass genera...

Abstract

The present invention is generally directed to a system for producing an algae biomass and wastewater that have reduced concentrations of contaminants. The algae and wastewater treated by the system of the present invention can be combined in a heterotrophic growth system in which the growth of the algae is increased due to the reduced concentration of contaminants. The algae grown in this manner also has a longer shelf life due to the lack of contaminants within the harvested algae.
